Linked scatter plots through vega?

Relevant to #75

One question is, how can one choose the right microbes? Right now the only way to do this is to select microbe by pointing and clicking through Emperor.

A better way is to first select by how many samples they are most abundance (i.e. their maximal samples) and see how their balances are correlated

For instance, we could have something like this (where microbes are points)


And selecting 2 points will inform something like this


It'll make this process a little more streamlined (its quite manual in notebooks atm). @fedarko, would this be something appropriate for qurro? If so, maybe able to contribute something.
